Social Insurance Calculator

The Social Insurance Calculator helps you calculate the four major social insurance premiums in South Korea based on an employee's monthly salary. It covers National Pension, Health Insurance, Long-term Care Insurance, and Employment Insurance, plus Industrial Accident Insurance — providing a complete breakdown of both employee and employer contributions. In South Korea, all businesses with one or more employees are required to enroll in the four major social insurance programs. The premiums are shared between the employee and employer at set ratios, with the employee's share being deducted from their monthly paycheck. The employer collects both shares and remits payments to the respective insurance agencies. This calculator uses 2026 rates and accounts for company-size-based Employment Insurance differentials as well as industry-specific Industrial Accident Insurance rates, giving you an accurate picture of total labor costs beyond base salary.

Step 1: Enter the monthly salary. Enter the employee's gross monthly pay before deductions. Exclude non-taxable items such as meal allowances (up to 200,000 KRW), vehicle subsidies, and childcare benefits, as these are not subject to insurance premiums. Step 2: Select the company size. The employer's Employment Insurance contribution varies based on company size due to additional job stability and skills development levies: • Under 150 employees: +0.25% additional • 150+ priority support enterprises: +0.45% additional • 150~999 employees: +0.65% additional • 1,000+ employees / Government: +0.85% additional Step 3: Enter the Industrial Accident Insurance rate. This rate varies widely by industry, from 0.7% (office work) to 18.6% (mining). Manufacturing typically falls between 1.0% and 2.0%, while construction is usually 3.5% or higher. Check the Korea Workers' Compensation & Welfare Service website for your exact rate. Step 4: Review the results. The calculator shows a summary of total employee and employer shares, a detailed per-insurance breakdown, and a visual bar chart comparing contributions.

National Pension (2026 rates): • Rate: Employee 4.5% + Employer 4.5% = 9.0% total • Base income range: Min 390,000 KRW ~ Max 6,170,000 KRW • If salary is below 390,000 KRW, 390,000 is used; if above 6,170,000, that cap is used • Formula: Capped salary × 4.5% (each side) Health Insurance (2026 rates): • Rate: Employee 3.545% + Employer 3.545% = 7.09% total • Formula: Monthly salary × 3.545% (each side) Long-term Care Insurance (2026 rates): • Rate: 12.95% of the Health Insurance premium • Split 50/50 between employee and employer • Formula: Health Insurance premium (employee portion) × 12.95% × 2, then split equally Employment Insurance (2026 rates): • Employee: Monthly salary × 0.9% • Employer: Monthly salary × 0.9% + company-size surcharge - Under 150: +0.25% - 150+ priority support: +0.45% - 150~999: +0.65% - 1,000+ / Government: +0.85% Industrial Accident Insurance: • Employer bears 100% of the cost • Formula: Monthly salary × accident rate (%)

1. Check Your Pay Stub: Review your monthly pay stub to verify insurance deductions match expected amounts. Discrepancies may arise from non-taxable allowance inclusions or different salary base calculations. 2. Rate Change Schedule: • Health & Long-term Care Insurance: Updated every January (announced in December) • National Pension: The 9% rate is fixed, but income caps are adjusted every July • Employment Insurance: Changed through legislation This calculator is updated whenever rates change. 3. Non-taxable Exclusions: Meal allowances (up to 200K KRW/month), personal vehicle subsidies (up to 200K), and childcare benefits (up to 200K) are excluded from the insurance premium base. 4. New Hires & Departures: Insurance premiums are charged on a monthly basis — not prorated by day. However, Health Insurance exempts the month of hire and charges the month of departure. 5. Durunnuri Subsidy: Businesses with fewer than 10 employees whose workers earn less than 2.7M KRW/month may qualify for the Durunnuri social insurance subsidy, which covers 80% of National Pension and Employment Insurance premiums — a significant savings for small businesses.
